In ornithological monitoring in areas planned for or hosting renewable energy installations, these criteria are crucial. Design decisions and mitigation measures should be based on clearly documented data on species distribution and breeding status.
Identifying breeding in the field is largely an inferential process, based on observing reproductive behaviours within appropriate phenological windows and in habitats typical of the species. Breeding-status categories organise observations by the likelihood of nesting: from records of non-breeding birds (e.g., juvenile), through possible and probable nesting, to direct evidence confirming breeding. This scale is a standard used in national studies and methodological guidelines for assessing breeding status, reflecting increasing certainty from indirect signs to direct proof.
Using this approach helps structure fieldwork, supports planning the number and timing of surveys, and standardises how observations are recorded and results presented. It ensures methodological consistency, transparency in interpretation, and comparability of results across seasons and areas.
The Ambiens team continuously tracks updates to guidelines and recommendations for monitoring and bird impact assessments, as well as relevant scientific and professional literature. In our work, we apply widely accepted scales and interpretive criteria, including breeding-status categories. As a result, our reports are clear, and our conclusions are firmly supported by field evidence and presented in a way that facilitates review by investors and regulatory authorities.
